WEBVTT 00:00.040 --> 00:01.840 Let's make the jumping to do so. 00:01.880 --> 00:03.920 We will open up our player script. 00:04.040 --> 00:06.680 So let's select the player GameObject in the hierarchy. 00:06.840 --> 00:10.200 And let's open up the player script by double clicking on it. 00:10.440 --> 00:14.360 And for that we're going to move over to this update function. 00:14.600 --> 00:17.720 So let's go there and we're going to do it over here. 00:18.080 --> 00:24.640 So what we will do uh we're going to create a variable in order to uh keep track of how many jumps we 00:24.640 --> 00:25.000 want. 00:25.040 --> 00:27.200 Since I want a double jump. 00:27.200 --> 00:30.000 So I'm going to create two variables for it. 00:30.000 --> 00:33.520 So let's go to the top of our class and let's make one. 00:33.640 --> 00:35.560 Uh sorry. 00:35.600 --> 00:38.120 We're going to make a one serialized field. 00:38.280 --> 00:42.240 So this will be serialized field private. 00:42.400 --> 00:45.160 And we're going to call this one this will be float. 00:45.160 --> 00:49.000 Or we can call this uh should be integer as well. 00:49.040 --> 00:52.480 But let's leave it with float variable. 00:52.680 --> 00:55.000 And we're going to call it extra jump. 00:55.000 --> 00:58.800 So let's call it extra jumps jumps. 00:58.800 --> 01:03.450 And let's create one more variable and we're going to make this one private. 01:03.610 --> 01:05.250 Uh, it doesn't need to be public. 01:05.250 --> 01:10.930 So we're just creating two these two variables to just keep track of how many jumps we want. 01:11.170 --> 01:15.290 So we're going to make private, uh, private float. 01:15.290 --> 01:18.010 And we can call this one total jumps. 01:18.050 --> 01:20.210 Total, uh, jumps. 01:20.250 --> 01:22.010 Let's call it total jumps. 01:22.370 --> 01:25.690 And let's close that up with semicolon and extra jump. 01:25.690 --> 01:28.490 By default I'm going to set equal to two f. 01:28.810 --> 01:33.890 Set equal to 2FYI set equal to two f since I want two jumps. 01:33.890 --> 01:34.730 So that's why. 01:35.010 --> 01:37.810 And I'm going to move over to this start function. 01:37.810 --> 01:41.210 So this start function get called in the start of the game. 01:41.210 --> 01:47.970 So in the start of the game what we want to do we're going to set our total jumps equal to our extra 01:47.970 --> 01:48.570 jumps. 01:48.730 --> 01:49.930 Extra jumps. 01:49.930 --> 01:52.170 So this total jumps right over here. 01:52.450 --> 01:54.170 By default it's going to be zero. 01:54.210 --> 02:00.550 But in the start of the game what we're doing we're just setting extra total jumps equal to our extra 02:00.550 --> 02:01.670 jumps, which is two. 02:01.710 --> 02:03.110 As you can notice. 02:03.110 --> 02:07.070 So this total jumps going to be two since this extra jumps is two. 02:07.390 --> 02:08.710 So now what. 02:09.110 --> 02:13.110 So what we're gonna do now we're going to move over to this update function. 02:13.110 --> 02:14.950 And over here we're going to check. 02:15.150 --> 02:17.150 So we're going to make this if condition. 02:17.150 --> 02:19.950 Let's make first bracket and some curly brackets. 02:20.110 --> 02:22.350 And what we want to check over here. 02:22.350 --> 02:28.950 We basically want to check if input if input dot get key down. 02:29.630 --> 02:31.350 And let's make first bracket. 02:31.350 --> 02:33.750 And we're going to pass Keycode key code. 02:33.790 --> 02:36.990 You can pass any key that you want to check with. 02:37.030 --> 02:40.430 So I'm going to pass key code dot space. 02:40.710 --> 02:45.430 My it's basically means if input dot get key down key code dot space. 02:45.430 --> 02:51.910 It basically means that if we press down space key on our keyboard at the same time we're going to check 02:51.950 --> 02:56.950 a, an an a, our total jumps if it's greater than zero. 02:57.360 --> 02:59.200 Basically we have total jumps. 02:59.200 --> 03:02.920 If that is the case, then we're going to make our player jump. 03:03.240 --> 03:07.960 So to make our player jump we can create a function for it. 03:07.960 --> 03:09.640 So let's make it over here. 03:10.000 --> 03:14.800 And that function uh we're going to call it later through a button. 03:14.800 --> 03:20.160 So that's why we're going to mark this function as public void for function. 03:20.160 --> 03:22.640 And we're going to call this function to something like jump. 03:22.640 --> 03:25.640 Let's make first bracket and some curly brackets. 03:25.880 --> 03:27.960 And what we want to do over here. 03:28.120 --> 03:30.760 We basically want to make our player jump. 03:30.760 --> 03:36.800 But before we make we need a reference of this rigid body 2D of this player game object. 03:36.800 --> 03:43.760 Because this rigid body 2D is responsible for velocity, adding force and all of those things. 03:43.760 --> 03:50.120 So that's why we need a reference of this rigid body 2D, uh, so we can make our player jump. 03:50.120 --> 03:54.360 So let's open up our player skip, and let's go to the top of our class. 03:54.360 --> 03:56.320 And let's grab the reference first. 03:57.020 --> 03:58.700 and it doesn't need to be public. 03:58.700 --> 04:00.460 So we're going to make it private. 04:00.620 --> 04:04.260 And the component we're looking for is a rigid body 2D. 04:04.300 --> 04:06.340 And let's call it something like RB. 04:06.500 --> 04:08.780 And let's move over to this start function. 04:08.780 --> 04:14.180 Because in the start of the game we want to grab the reference since we made this field private. 04:14.180 --> 04:18.540 So we're not going to notice underneath our player skip right over here. 04:18.540 --> 04:23.860 So that's why we're gonna do with start function to keep our code a little bit clean. 04:24.180 --> 04:28.060 So what we will do we will use this this dot get component. 04:28.260 --> 04:31.460 And the component we're looking for is a rigid body 2D. 04:31.460 --> 04:35.060 So we're going to pass this rigid body 2D and make this first bracket. 04:35.260 --> 04:41.700 So what we simply doing we just taking our rigid body 2D basically this rigid body 2D of this player 04:41.740 --> 04:42.540 game object. 04:42.540 --> 04:49.540 And now what we're gonna do, we're gonna store this rigid body 2D into this RB field, this rigid body 04:49.540 --> 04:49.940 RB. 04:50.100 --> 04:54.380 So we basically just taking that and now we're going to store it. 04:54.660 --> 04:58.070 So let's store into this RB equal to this. 04:58.070 --> 05:00.750 Basically we're taking this rigid body 2D. 05:00.790 --> 05:05.830 If I move over to unity editor we basically taking this rigid body 2D. 05:05.830 --> 05:08.430 This basically is just referencing itself. 05:08.630 --> 05:13.710 And we're just taking this rigid body 2D component which is dot get component. 05:13.710 --> 05:18.430 And we storing this rigid body 2D into this RB as you can see. 05:18.630 --> 05:21.270 And now we're going to move over to this jump function. 05:21.430 --> 05:27.270 So over here what we're gonna do we're going to create a vector to a vector two. 05:27.310 --> 05:30.390 And we can call this one something like velocity. 05:30.510 --> 05:34.710 And let's set equal to rv dot linear velocity. 05:34.750 --> 05:37.070 We need to set this linear velocity. 05:37.350 --> 05:40.350 So uh before it was something like velocity. 05:40.510 --> 05:45.990 But in unity six we have to type this RB dot linear velocity. 05:46.270 --> 05:49.310 And now what we're going to do we're going to make a uh sorry. 05:49.350 --> 05:51.310 We will uh go to velocity. 05:51.470 --> 05:53.350 And then we're going to access the Y. 05:53.470 --> 05:57.880 And we will set equal to some, uh, some around something like ten F. 05:58.080 --> 06:04.840 And after setting that we're going to set RV dot linear velocity equal to our velocity. 06:04.840 --> 06:06.040 So let me explain. 06:06.320 --> 06:13.080 Firstly we just setting uh this we just created this vector to velocity which gonna have x axis and 06:13.080 --> 06:14.040 y axis. 06:14.040 --> 06:17.920 So we setting equal to rb dot linear velocity. 06:17.960 --> 06:23.160 Basically we just going over to this rigid body 2D of this player uh game object. 06:23.160 --> 06:28.960 And we taking the linear velocity of it and we storing into this vector to velocity. 06:29.160 --> 06:33.200 And after that we basically want to jump in the y axis. 06:33.200 --> 06:37.440 So if I select this move tool we only want to jump in the y axis. 06:37.440 --> 06:40.640 So that's why we just only access the y. 06:40.680 --> 06:43.240 As you can see velocity dot y. 06:43.640 --> 06:48.360 And you can access the x axis as well like velocity dot x. 06:48.520 --> 06:53.900 Since we jump over the uh, since we want our jump in the y axis only. 06:53.900 --> 06:58.700 So that's why we access the velocity dot y and we set equal to ten. 06:58.700 --> 07:05.460 And after that once again we just, uh, going over to this linear velocity of this rigid body 2D of 07:05.460 --> 07:12.220 this player game object, and we say, uh, we just setting equal to velocity after only modifying the 07:12.220 --> 07:15.380 y axis with ten unit, as you can see. 07:15.380 --> 07:18.340 So we're going to jump in the y axis with ten unit. 07:18.460 --> 07:23.340 Firstly we created the variable which is vector to velocity. 07:23.340 --> 07:29.660 And after modifying the y axis we again setting velocity are basically rigid body velocity. 07:29.660 --> 07:35.260 Linear velocity equal to this velocity after modifying the y axis only. 07:35.260 --> 07:39.260 And now what we're going to do we're going to call this jump function over here. 07:39.580 --> 07:45.780 So once we press down space key on our keyboard at the same time total jumps is greater than zero. 07:45.780 --> 07:50.980 And we do know that in the start of the games this total jumps just gonna be two, since we're setting 07:50.980 --> 07:52.270 equal to extra jump, jam. 07:52.310 --> 07:55.630 As you can see and extra jams, by default we set two. 07:55.670 --> 07:57.710 So this one over here is two. 07:57.750 --> 08:00.070 So that's why this total jump is going to be two. 08:00.310 --> 08:02.710 So total jumps will be greater than zero. 08:02.750 --> 08:04.910 Basically means this condition is true. 08:04.910 --> 08:06.910 And also we press down space key. 08:07.070 --> 08:09.110 Then what we want we want jump. 08:09.110 --> 08:11.910 So we're going to call this jump function and jump function. 08:11.910 --> 08:13.670 Just just going to do these things. 08:13.670 --> 08:20.150 It's basically just going to make our player jump in the y axis with ten unit as you can see. 08:20.150 --> 08:22.550 So let's call the jump function over here. 08:22.870 --> 08:24.710 And let's make a first bracket. 08:24.710 --> 08:26.830 And then close that up with semicolon. 08:26.830 --> 08:34.670 And after jumping what we want we want to subtract from this total jumps since we made our jump. 08:34.670 --> 08:36.990 So we can subtract by one unit. 08:36.990 --> 08:41.350 So we will set our total jumps minus equal one. 08:41.710 --> 08:43.270 Basically we just subtracting. 08:43.310 --> 08:45.590 Or you can simply do minus minus. 08:45.590 --> 08:49.110 It's basically means the same thing which is subtracting one. 08:49.110 --> 08:54.810 So if we press down space key on our keyboard at the same time, total jumps is zero. 08:54.810 --> 08:58.130 So if we press done for the first time, then we're going to make jump. 08:58.130 --> 09:00.090 So this total jumps is two. 09:00.210 --> 09:02.450 So two minus one is just going to be one. 09:02.450 --> 09:09.890 And if we press down second time on our keyboard space key then this right over here total jumps is 09:09.890 --> 09:10.330 one. 09:10.330 --> 09:16.610 So which will be still greater than zero or greater than zero means we will be able to jump for the 09:16.610 --> 09:20.610 next time as well since this total jumps is one. 09:20.970 --> 09:24.490 So we jumping and after jumping once again we subtracting. 09:24.490 --> 09:26.570 So one minus one gonna be zero. 09:26.570 --> 09:32.810 And if we press down space key third time and and now this total jumps is zero. 09:32.810 --> 09:34.810 And zero is not greater than zero. 09:34.850 --> 09:37.090 Zero is equals equals to zero. 09:37.130 --> 09:43.330 Basically this condition over here becomes false means we're not going to able to jump since the in 09:43.410 --> 09:46.650 this end condition put this condition should be true. 09:46.690 --> 09:52.860 Else we're not gonna basically we're not gonna able to make our player jump for the third time. 09:53.180 --> 09:59.220 So I hope you get the idea that what we're doing over here, and now we're gonna press down Ctrl s to 09:59.260 --> 10:00.420 save our skip. 10:00.460 --> 10:02.460 And now let's move over to unity. 10:02.660 --> 10:05.220 So we will be able to notice our player. 10:05.220 --> 10:07.940 Just gonna make two jumps two jumps. 10:07.940 --> 10:14.460 And it's not going to make the third jumps because we set our total jumps to extra jumps, which is 10:14.460 --> 10:18.820 by default we set equal to two since we want to jump. 10:18.860 --> 10:23.700 But if you want triple jumps then you can set a extra jumps to three. 10:23.700 --> 10:27.060 So that's why we mark that variable as serialized field. 10:27.060 --> 10:30.220 So we can notice underneath our player skip. 10:30.220 --> 10:31.860 So just wait a little moment. 10:31.860 --> 10:36.540 Once it's compiled we can see uh, we can notice underneath our player skip. 10:36.580 --> 10:43.140 As you can see, as soon as our player skip gets compiled extra jumps big as by default we set two. 10:43.300 --> 10:49.640 And now if we click on this play button in the top in order to play our game and press down space key 10:49.680 --> 10:50.920 on our keyboard. 10:50.920 --> 10:57.680 You will see our player just jump in the Y axis with ten units, as we said, and we're just gonna able 10:57.680 --> 10:58.680 to jump two times. 10:58.680 --> 11:01.600 So if I press run first, then second, as you can see. 11:01.880 --> 11:08.520 But if I try to press down space key on my keyboard, it's not jumping at all. 11:08.520 --> 11:08.920 Why? 11:09.080 --> 11:15.200 Because if we move over to unity, uh, sorry, uh, code, uh, this total jumps became zero. 11:15.240 --> 11:19.000 We just loses all of our jumps after jumping. 11:19.000 --> 11:21.280 We just subtracting, as you can see. 11:21.280 --> 11:24.480 So this total jumps is now something like zero. 11:24.480 --> 11:31.360 So once it is zero then we're gonna set back again to our total jumps to extra jump. 11:31.360 --> 11:34.960 So we can able to jump for the next time as well. 11:35.280 --> 11:40.200 So what we need to do we're going to create a variable, uh, something like scrum. 11:40.200 --> 11:46.840 And that will be a bool variable to just keep track of if this player is standing on this ground or 11:46.840 --> 11:47.360 not. 11:47.360 --> 11:48.850 So we're gonna to do that. 11:48.850 --> 11:55.050 So if it's standing on this ground then we're going to set our uh this total jumps to our extra jumps 11:55.050 --> 11:55.890 one more time. 11:55.890 --> 11:57.810 So this condition just going to be true. 11:57.810 --> 12:02.770 So we are just going to make, uh, our player jump, uh, one more time. 12:02.930 --> 12:05.130 One more time, basically two times. 12:05.170 --> 12:09.410 Uh, we can able to jump once we are standing on that ground. 12:09.410 --> 12:11.570 So we're going to create a variable for it. 12:11.570 --> 12:15.490 So let's get out of play mode and let's move over to our script. 12:15.770 --> 12:18.730 And for that we will go to top of our class. 12:18.730 --> 12:20.370 And it doesn't need to be public. 12:20.370 --> 12:22.770 So we can simply make it private. 12:22.770 --> 12:27.530 So this will be private and that will be pool which can be true or false. 12:27.770 --> 12:33.810 And uh, this variable just going to keep track of if we are standing on that ground or not. 12:33.810 --> 12:37.890 So we can say we're going to say something like is ground. 12:38.090 --> 12:41.050 And uh, and let's close that up with semicolon. 12:41.050 --> 12:47.980 So basically what we want to do, we basically want to uh, create a, we will create a point somewhere 12:47.980 --> 12:48.940 around here. 12:48.940 --> 12:51.780 And from that point we're going to create a circle. 12:51.780 --> 12:58.180 And if that circle collide with this ground, then we're going to set our total jumps to our extra jump. 12:58.220 --> 13:03.380 Basically, we just want our player to jump if that circle collides with this ground. 13:03.780 --> 13:05.420 So we're going to create the circle. 13:05.420 --> 13:07.500 So let's create an tile game object. 13:07.500 --> 13:10.700 And from that point we will create our circle. 13:10.700 --> 13:15.500 And if that circle collides with this ground then we're going to make our player jump. 13:15.500 --> 13:19.420 Else we not gonna make it because the player will be in the air. 13:19.420 --> 13:20.260 So that's why. 13:20.660 --> 13:22.140 So let's create a point. 13:22.140 --> 13:25.540 So we will select our player GameObject in the hierarchy. 13:25.580 --> 13:26.820 Let's right click on it. 13:26.820 --> 13:29.300 And let's create an empty game object. 13:29.300 --> 13:32.900 And we will call this GameObject to something like Round Check. 13:33.060 --> 13:34.940 So let's call it Ground Check. 13:35.340 --> 13:37.660 And let's select the move tool from here. 13:37.660 --> 13:41.140 And let's move it in the bottom somewhere around here. 13:42.220 --> 13:44.700 And we're going to choose an gizmos for it. 13:44.700 --> 13:47.000 So let's choose this one. 13:47.600 --> 13:49.680 And this seems fine. 13:50.240 --> 13:53.640 And so from this point we want to create the circle. 13:53.640 --> 13:59.760 So let's open up our script and we're going to do it over here inside this update function. 13:59.760 --> 14:01.360 So let's do it here. 14:01.720 --> 14:04.480 Let's do it before this if condition. 14:04.960 --> 14:13.600 So what we're going to do to create circle we need to use this physics 2D physics 2D dot overlap circle 14:13.840 --> 14:20.560 overlap circle sorry physics 2D overlap circle. 14:20.800 --> 14:26.720 And this function over here as a first argument, it's going to take the point from where we want to 14:26.720 --> 14:28.760 create the circle or the position. 14:28.760 --> 14:31.760 So we're going to create the circle from this ground check point. 14:32.120 --> 14:34.920 And the second thing it's going to take the radius. 14:34.960 --> 14:40.480 And the third argument it's going to take the layer mask basically which game object we want to target 14:40.480 --> 14:42.400 since we want to target this ground. 14:42.400 --> 14:45.810 So we need to assign this ground as a ground layer. 14:45.810 --> 14:52.330 But before we do so, let's make this comment and comment and don't interrupt our quotes. 14:52.330 --> 14:59.730 So basically just type, uh, just uh, type two forward slashes and let's go to top of our class because 14:59.730 --> 15:02.730 we need to, uh, grab those, uh, things. 15:02.730 --> 15:05.930 So first thing, what we need, uh, we need a point. 15:05.930 --> 15:08.690 So let's make a serialize field private. 15:08.970 --> 15:15.490 And for point or position, we're going to type transform, which is responsible for position or point. 15:15.970 --> 15:23.450 And uh, and we can call this one ground check ground check point, something like that. 15:23.650 --> 15:25.930 And the second thing we need the radius. 15:25.930 --> 15:30.970 So let's make a another class field private, uh, float. 15:30.970 --> 15:35.250 And we can call this one check radius radius. 15:35.250 --> 15:38.690 And by default I'm going to set something like point two. 15:39.050 --> 15:44.950 Uh, if a smaller number and the third argument, it's going to take the layer mask or which game object 15:44.950 --> 15:46.150 we want to target. 15:46.150 --> 15:48.990 So in our case we're gonna target this crown. 15:49.750 --> 15:52.990 So as a layer mask we're gonna choose that crown. 15:52.990 --> 15:58.790 But before we do let's assign so serialize fill private layer mask. 15:58.990 --> 16:07.110 And we're going to call this one target layer or let's call it what is Crown as simply what is Crown. 16:07.590 --> 16:09.670 And let's close that up with semicolon. 16:09.670 --> 16:12.270 Let's press down Ctrl S to save our script. 16:12.270 --> 16:14.190 And now let's move over to unity. 16:14.710 --> 16:17.590 So now let's hope it's gonna work. 16:17.630 --> 16:22.710 Basically underneath our player skip we will able to notice those variables. 16:22.710 --> 16:26.150 So the first thing will be our crown check point. 16:26.150 --> 16:28.390 So we need to select our crown check. 16:28.390 --> 16:30.710 And we need to drag it in that slot. 16:30.710 --> 16:32.550 So we will have the point. 16:32.590 --> 16:37.190 So as you can see as soon as our player skip compiles crown check point. 16:37.190 --> 16:39.990 And it says none transform basically empty. 16:40.030 --> 16:43.480 So we're going to take our crown check underneath our player game object. 16:43.480 --> 16:46.040 Let's drag it there and check radius. 16:46.040 --> 16:48.280 By default we just given 0.2. 16:48.320 --> 16:53.560 You can just go with any number that you like, but make sure you go with smaller. 16:53.560 --> 16:54.520 And what is ground? 16:54.520 --> 16:59.840 We're gonna choose our ground, but before we choose our ground, we need to assign this ground as a 16:59.840 --> 17:00.840 ground layer. 17:00.840 --> 17:02.280 So how we can do that? 17:02.280 --> 17:06.120 Firstly, we need to select our GameObject in the hierarchy first. 17:06.120 --> 17:07.640 Then go over to Inspector. 17:07.640 --> 17:10.760 In the top right you can see layer and it says default. 17:10.760 --> 17:13.520 So just click there and then click on Add Layer. 17:13.800 --> 17:15.640 And we're gonna add a new layer. 17:15.840 --> 17:18.200 And you can name the layer whatever you want. 17:18.240 --> 17:20.480 So I'm going to call it ground. 17:20.640 --> 17:22.160 So let's call it ground. 17:22.280 --> 17:25.640 And let's select our player script one more time. 17:25.640 --> 17:26.760 And what is ground. 17:26.760 --> 17:27.720 As you can see. 17:27.760 --> 17:28.360 Sorry. 17:28.400 --> 17:29.840 We're gonna choose our ground. 17:29.840 --> 17:32.880 And we need to assign this ground as a ground layer. 17:32.880 --> 17:34.280 So we already created. 17:34.280 --> 17:37.920 So we're going to choose our GameObject one more time in the hierarchy. 17:38.080 --> 17:39.640 Then go over to Inspector. 17:39.680 --> 17:41.720 As you can see layers is default. 17:41.770 --> 17:43.130 so we will choose ground. 17:43.170 --> 17:46.250 Now we assign it this ground as a ground layer. 17:46.290 --> 17:48.370 Now we will select our player skip. 17:48.370 --> 17:49.450 And what is ground. 17:49.450 --> 17:50.970 We're going to choose our ground. 17:51.010 --> 17:54.250 Now the circle only going to check for with this ground. 17:54.530 --> 17:57.810 And we just assign it all of the variables. 17:57.810 --> 17:59.970 And we are ready to create that. 17:59.970 --> 18:03.290 So let's open up our player script by double clicking on it. 18:03.930 --> 18:06.210 And let's remove these two slashes. 18:06.370 --> 18:08.170 And let's use this function. 18:08.170 --> 18:10.410 So this overlap as a first argument. 18:10.410 --> 18:13.970 It's going to take the point from where we want to create the circle. 18:13.970 --> 18:20.090 So we're going to pass our ground checkpoint dot position and ground checkpoint dot position. 18:20.130 --> 18:21.610 We do know that ground check. 18:21.650 --> 18:25.050 We just pass our ground checkpoint as you seen. 18:25.290 --> 18:27.490 And the second thing it's going to take the radius. 18:27.490 --> 18:29.890 So we will pass our check radius. 18:29.890 --> 18:32.450 And the third argument it's going to take the layer mask. 18:32.450 --> 18:36.130 So we will pass our what is ground and what is ground. 18:36.130 --> 18:38.010 We have chosen our ground. 18:38.010 --> 18:40.130 And let's close that up with semicolon. 18:40.130 --> 18:45.830 So this function right over here, it's gonna create the circle around this ground check point with 18:45.830 --> 18:49.470 this much of radius and just going to target our ground. 18:49.470 --> 18:52.990 So it's gonna create a somewhere around here. 18:53.230 --> 18:58.510 And if that circle really collide with this ground, then this function over here, it's going to give 18:58.550 --> 18:59.430 a true value. 18:59.470 --> 19:01.830 Else it's going to give a false value. 19:01.830 --> 19:06.550 So what we will do we're going to store that result into this ground parameter. 19:06.550 --> 19:12.750 Basically we created this parameter to just keep track of if this player is standing on this ground 19:12.750 --> 19:13.270 or not. 19:13.310 --> 19:17.510 If it's uh, then uh, then we want we gonna make jump. 19:17.510 --> 19:23.710 So what we will do, we will set our is crown is crown equal to this. 19:23.950 --> 19:31.190 So this, uh, basically this physics 2D dot overlap circle can be true or false depending upon if the 19:31.190 --> 19:34.150 circle is really colliding with this crown or not. 19:34.190 --> 19:36.670 Let's suppose the circle collide with this ground. 19:36.670 --> 19:39.310 So this function over here, it's gonna be true. 19:39.310 --> 19:43.160 So And which setting is ground equal to this as you can see. 19:43.160 --> 19:47.200 So that's why this is ground going to be true and is ground going to be true. 19:47.200 --> 19:52.240 And let's suppose the circle don't collide with this round. 19:52.400 --> 19:56.840 And then this function over here it's going to give us a false value. 19:56.840 --> 19:59.520 So that's why this is ground right over here. 19:59.520 --> 20:00.760 It's going to be false. 20:01.120 --> 20:02.280 It's going to be false. 20:02.680 --> 20:03.880 So what we will do. 20:04.040 --> 20:10.280 And we created this parameter to just keep track of in in order to standing on this ground or not. 20:10.600 --> 20:15.920 And if this ground is true basically means this player is standing on this ground. 20:15.920 --> 20:19.480 So what we need to do, we need to set our extra jumps. 20:19.600 --> 20:22.520 Sorry, total jumps to our extra jumps. 20:22.760 --> 20:24.880 Uh, since we are standing on this ground. 20:24.880 --> 20:25.840 So that's why. 20:26.200 --> 20:31.080 So what we're gonna do now, we're going to check, uh, so we will use this if condition. 20:31.080 --> 20:36.160 Let's make first bracket and some curly brackets and what we want to check over here, we're going to 20:36.160 --> 20:43.620 check if is ground is equals Equals to true basically means that that player is standing on this ground 20:43.620 --> 20:46.580 or the circle really colliding with this ground. 20:46.580 --> 20:53.220 So what we need to do now, we basically need to set our, uh, total jumps to our extra jumps. 20:53.220 --> 20:58.900 And we do know once we're going to set back, uh, so we will able to jump, uh, for the next time 20:58.900 --> 21:05.340 as well, we can make double jump for the next time, or you can just leave it like this, uh, is ground. 21:05.340 --> 21:09.140 It's also basically means true means we are standing on this ground. 21:09.140 --> 21:14.540 So now what we're going to do, we're going to set our total jumps equal to our extra jumps. 21:14.820 --> 21:17.020 And let's close that up with semicolon. 21:17.140 --> 21:20.540 And now we're going to press down Ctrl S to save our script. 21:20.540 --> 21:22.500 And now let's move over to unity. 21:22.780 --> 21:29.380 And we will able to notice as soon as this player just gonna stand on this ground or the circle collide 21:29.380 --> 21:34.780 with this, uh, ground, then we just setting extra total jumps to our extra jumps. 21:34.780 --> 21:38.030 Basically, we simply just making jump. 21:38.870 --> 21:44.350 Uh, we just created that parameter to just keep track of if we're standing on this ground or not. 21:44.550 --> 21:51.790 Uh, but it would be nice if we able to see our circle, uh, to the C circle or to draw the circle, 21:51.790 --> 21:55.230 we need to use another inbuilt function of unity. 21:55.430 --> 21:57.190 So let's open up our player. 21:57.190 --> 22:00.270 Skip one more time and let's do it in the bottom. 22:00.270 --> 22:02.350 You can do it anywhere you want. 22:02.590 --> 22:06.750 And make sure you just do as I as I have done over here. 22:06.870 --> 22:10.270 It's a void Ondraw Cosmo selected function. 22:10.270 --> 22:15.590 So this function gets called when, uh, sorry, it's called by unity itself. 22:15.750 --> 22:19.230 And this function just gonna draw whatever you want to draw. 22:19.390 --> 22:22.630 So what we're going to do, we're going to draw the circle. 22:22.630 --> 22:30.230 So that's why we're going to use this gizmos dot draw where sphere function and this function just gonna 22:30.270 --> 22:31.230 draw the circle. 22:31.430 --> 22:35.950 So first thing it's going to take the point from where we want to create the circle. 22:35.950 --> 22:39.080 So we will pass our ground checkpoint position. 22:39.080 --> 22:39.720 From there. 22:39.720 --> 22:41.520 We want to create the circle. 22:41.520 --> 22:44.200 And the second thing it's going to take the radius. 22:44.200 --> 22:46.640 So we will pass our check radius. 22:46.640 --> 22:48.840 And let's close that up with semicolon. 22:48.840 --> 22:51.640 But before we draw the circle we need to check. 22:51.680 --> 22:56.600 Let's suppose if you haven't dragged this ground check to this ground check field basically means this 22:56.600 --> 22:59.360 ground check point is empty means none. 23:00.040 --> 23:04.600 So over here, as you can see, we still are using this function. 23:04.600 --> 23:07.000 And we're just trying to finding that position. 23:07.000 --> 23:09.880 And we're drawing the circle with this much of radius. 23:09.880 --> 23:15.040 And if you haven't assigned so this function not going to able to find this ground check point. 23:15.040 --> 23:17.800 So that's why it's gonna throw us an error. 23:17.800 --> 23:23.680 So before we draw the circle we need to check if we assign it our ground check point or not. 23:23.680 --> 23:31.240 So that's why before we draw, we will check if our ground checkpoint, if it's not equal to null, 23:31.760 --> 23:32.960 not equal to null. 23:32.960 --> 23:35.000 Let's make this a curly brackets. 23:35.000 --> 23:36.580 Then we're going to draw the circle. 23:36.580 --> 23:42.620 So we're gonna cut this by control X and we're going to paste it inside the control V. 23:42.820 --> 23:49.260 So what we simply have done over here, we basically checking if our ground check point is not equal 23:49.260 --> 23:54.020 to null basically means that we just drag this ground check to this ground check. 23:54.020 --> 23:56.060 And this field is not empty. 23:56.100 --> 24:00.260 Then what we're doing then we're just drawing the circle, as you can see. 24:00.260 --> 24:04.100 So before you draw the circle make sure you assign it. 24:04.100 --> 24:06.660 So that's why we're using this if condition. 24:06.900 --> 24:11.060 And if you want to choose another color you want to draw with. 24:11.060 --> 24:13.540 So before you draw you can select the color. 24:13.540 --> 24:19.380 And in order to select the color you can use this gizmos dot color equal to color that you like. 24:19.380 --> 24:21.940 So I'm going to set color dot yellow. 24:22.220 --> 24:24.420 And let's close that up with semicolon. 24:24.420 --> 24:27.740 And now we're going to press down Ctrl S to save our script. 24:27.740 --> 24:31.660 And this function automatically gonna call by unity itself. 24:31.860 --> 24:36.070 And it's going to draw the circle Uh, from our from checkpoint. 24:36.710 --> 24:43.470 And now we're going to able to notice that circle, and we can play around with our, uh, check radius, 24:43.510 --> 24:46.990 uh, in order to adjust the radius of that circle. 24:47.270 --> 24:48.870 So just wait a little moment. 24:48.870 --> 24:56.790 As you can see, as soon as our script compiles, we can notice, uh, our, uh, circle from this ground 24:56.790 --> 24:57.470 check point. 24:57.470 --> 25:04.750 And we can make this a little bit small by playing around with or just messing with this check radius. 25:04.750 --> 25:09.790 We can make it even more smaller, but I'm going to leave with 0.2. 25:10.390 --> 25:12.390 Basically, choose a smaller number. 25:12.830 --> 25:16.390 And now we should able to see. 25:16.670 --> 25:23.670 So if I just press uh click play button in the top you will see uh, sorry. 25:24.630 --> 25:30.550 Uh, you will see that as soon as we're gonna collide with this, uh, ground or just gonna stand on 25:30.550 --> 25:33.650 this ground, we will able to notice this player will jump. 25:33.690 --> 25:36.330 Else it's not gonna make jump at all. 25:36.330 --> 25:37.770 So if I press down space key. 25:37.810 --> 25:44.770 As you can see, we only able to make jump once the circle is colliding with this ground and we only 25:44.770 --> 25:47.170 just are making two jumps. 25:47.170 --> 25:49.690 As you can see, not more than that. 25:49.810 --> 25:52.490 One, two and not more than that. 25:52.490 --> 25:58.210 But as soon as this player just colliding with this ground or this circle collide with this ground, 25:58.250 --> 26:04.530 we able to make jump because we just setting this total jumps to our extra jumps, which is two. 26:04.810 --> 26:08.010 And let's suppose you set it to one extra jumps. 26:08.010 --> 26:12.530 So if I set to one we just gonna only able to make one jump. 26:12.530 --> 26:15.970 As you can see we not making more than that. 26:16.210 --> 26:16.690 Sorry. 26:16.730 --> 26:20.130 We sometimes making because the circle is too much big. 26:20.410 --> 26:22.770 And let's suppose we want to make three jumps. 26:22.770 --> 26:30.370 So if we put our extra jumps to three so we can make three jumps as you one two, three as you can see. 26:30.730 --> 26:38.100 So I hope you get the idea that how you can make the jump, and it would be nice if we are able to notice 26:38.460 --> 26:45.540 or adjust our jump height in underneath our player skip, and we don't need to go to that skip and change 26:45.540 --> 26:51.140 the, uh, change the jump height, uh, or basically that thing. 26:51.140 --> 26:54.980 So we're going to get out of play mode and we will open up our player skip. 26:54.980 --> 27:01.900 And instead of setting directly or hard coding this like over here, as you can see, velocity dot y 27:02.060 --> 27:04.220 we just set equal to ten f. 27:04.260 --> 27:10.700 Instead of doing that, let's make a variable to uh, and we can just gonna make that public or say 27:10.700 --> 27:14.220 less fill so we can adjust underneath our player skip. 27:14.220 --> 27:20.380 So we don't need to come to the script and change this value over again and again to match up the correct 27:20.420 --> 27:21.140 jump height. 27:21.180 --> 27:28.780 So we will go to top of our class and let's make another serialized field, serialized field a private. 27:28.780 --> 27:30.980 And we're going to call this one something. 27:31.200 --> 27:32.360 This will be float. 27:32.360 --> 27:34.640 And let's call this one jump height. 27:34.680 --> 27:36.520 So let's call it jump height. 27:36.520 --> 27:39.120 And by default I'm going to set equal to 12. 27:39.560 --> 27:41.640 And let's close that up with semicolon. 27:41.640 --> 27:45.320 And now we're going to replace this with our jump height. 27:45.320 --> 27:47.960 So let's pass our jump height sorry. 27:48.440 --> 27:53.240 Jump height and jump height by default set with 12. 27:53.240 --> 27:57.280 So we will able to jump in the y axis with 12 unit. 27:58.400 --> 28:02.120 And now we're going to press down Ctrl S to save our skip. 28:02.120 --> 28:04.320 And now let's move over to unity. 28:04.680 --> 28:11.000 So in the Y we will able to make jump with a jump height parameter. 28:11.200 --> 28:13.320 And by default we set it to 12. 28:13.360 --> 28:15.680 But we just made it a serialized field. 28:15.680 --> 28:19.920 So we can notice underneath our player skip right over here. 28:20.200 --> 28:25.760 So as you can notice right over here jump height which is by default we set 12. 28:25.760 --> 28:29.160 So I'm going to make it a little bit bigger something like 15. 28:29.360 --> 28:33.570 And I want to decrease the radius of this circle. 28:33.730 --> 28:39.610 So I'm going to go with something like .1.15 something like that. 28:39.770 --> 28:41.770 And now this seems perfect. 28:42.090 --> 28:43.810 And also extra jumps. 28:43.850 --> 28:46.730 I want to so I'm going to leave it extra jumps to two. 28:47.170 --> 28:48.690 And let's go to overrides. 28:48.690 --> 28:51.170 And then make sure you click on this apply all. 28:51.170 --> 28:54.970 If you turn it your player game object into a prefab. 28:55.290 --> 28:59.330 And if we just go ahead and then click on this play button in the top. 28:59.490 --> 29:01.410 By now it would be fine. 29:01.450 --> 29:02.810 It's just gonna be fine. 29:02.930 --> 29:09.370 So whenever we're touching our ground or this player just touching our ground, then we're just setting 29:09.370 --> 29:11.490 our total jumps to extra jumps. 29:11.530 --> 29:12.610 As you can see. 29:12.610 --> 29:14.250 So we're making too much. 29:14.250 --> 29:16.210 So I'm going to make jump height to ten. 29:16.570 --> 29:19.330 And we're making so as you can see. 29:19.330 --> 29:20.970 So this seems pretty much cool. 29:20.970 --> 29:22.650 So I hope you get the idea. 29:22.690 --> 29:24.370 And let me explain one more time. 29:24.370 --> 29:26.050 So I'm gonna get out of play mode. 29:26.050 --> 29:28.170 So if I move over to my script. 29:28.170 --> 29:34.740 So so this function over here, just creating that circle from that ground check point with this much 29:34.740 --> 29:37.100 of radius and targeting our ground. 29:37.100 --> 29:38.980 So this can be true or false. 29:39.140 --> 29:44.420 And if the circle is really colliding with this ground, then this over here gonna be true. 29:44.580 --> 29:47.900 And that's why this is ground, uh, just gonna be true. 29:47.900 --> 29:53.380 And we created this variable to just keep track of if we're standing on this ground or not. 29:53.540 --> 29:58.780 And if it's then what we're doing if this ground is true, basically means that circle is colliding 29:58.780 --> 30:04.140 with that ground, then we're setting total jumps to our extra jumps and to extra jumps. 30:04.140 --> 30:05.860 By default we set two. 30:05.900 --> 30:08.300 So this total jumps gonna be two. 30:08.500 --> 30:15.420 And so this an end condition basically this condition getting true once again because total jump is 30:15.540 --> 30:18.860 uh is true once our s ground parameter is true. 30:18.860 --> 30:20.820 Basically standing on that ground. 30:20.820 --> 30:23.460 And we do know that two is greater than zero. 30:23.700 --> 30:25.500 So that's why we're making jump. 30:25.500 --> 30:31.160 And after jumping we just subtracting from their total jumps one unit, as you can see. 30:31.160 --> 30:34.320 So it's going to be one and once it's one. 30:34.320 --> 30:39.360 And if we press down space key on our keyboard and total jumps is greater than zero. 30:39.800 --> 30:41.640 So this total jumps is one. 30:41.640 --> 30:43.280 So one is greater than zero. 30:43.480 --> 30:46.560 So the condition the condition is still true. 30:46.680 --> 30:48.360 So that's why we jumping. 30:48.400 --> 30:50.360 And once again we subtracting. 30:50.360 --> 30:52.600 So one minus one is just going to be zero. 30:52.600 --> 30:56.840 And now if we jump this total jumps is zero. 30:56.840 --> 30:59.200 And zero is not greater than zero. 30:59.200 --> 31:05.080 So that's why we are not able to jump for the third time or that we're making a jumping. 31:05.080 --> 31:11.640 But as soon as we colliding with this ground, as you can see, we setting total jumps equal to our 31:11.680 --> 31:13.320 extra jumps, which is two. 31:13.360 --> 31:16.000 So this total jumps becomes one more time to. 31:16.120 --> 31:21.800 So this end condition right over here becomes one more time to true to true. 31:21.800 --> 31:24.840 So that's why we able to make our player jump. 31:25.000 --> 31:31.010 So I hope you get the idea that how you can make jam and you can make jam as many times as you want, 31:31.210 --> 31:38.330 and it would be nice if we just give it a title somewhere over here, uh, underneath our player, skip 31:38.490 --> 31:39.890 over here a title. 31:40.010 --> 31:43.450 And in order to give a title, we need to use header. 31:43.450 --> 31:45.610 So we will open up our player skip. 31:45.810 --> 31:48.170 And we will go to top of our class. 31:48.410 --> 31:56.450 And over here, uh, so this right over here I'm going to put this line of code, this one uh, by hold 31:56.490 --> 31:57.850 down alt on your keyboard. 31:57.850 --> 32:02.810 And you can use up and down arrow in order to move your, uh, line of code. 32:03.010 --> 32:07.250 And so this, uh, all of these things right over here is jumping. 32:07.570 --> 32:10.290 Uh, so that's why I'm gonna give a title. 32:10.330 --> 32:15.810 To give a title, we need to make this square brackets, and we need to type this header, and we need 32:15.810 --> 32:17.130 to make this brackets. 32:17.130 --> 32:22.370 And inside this bracket in quotation, you can just give the title that you want. 32:22.410 --> 32:30.510 So so since this this all of this variable is for jumping, so I'm going to call it player jump section. 32:30.510 --> 32:33.190 Or simply we can call it jump as well. 32:33.310 --> 32:40.350 And now if we press down space sorry Ctrl s on our keyboard in order to save our skip and then move 32:40.350 --> 32:48.350 over to unity underneath our player skip, we will notice a title, a title, something says player 32:48.350 --> 32:50.270 jump as we have given. 32:50.270 --> 32:50.710 So. 32:50.950 --> 32:53.910 So you need to use a square brackets then header. 32:53.910 --> 32:59.030 And inside that brackets you basically need to put quotation and then the title. 32:59.030 --> 33:03.630 As you can see underneath our player skip we can say player jump title. 33:03.630 --> 33:08.990 And underneath we can see all of the things variables for our jumping. 33:09.350 --> 33:11.670 And we can it's just make it cool. 33:11.670 --> 33:12.550 So that's why. 33:12.830 --> 33:18.550 And we will go to overrides and then apply all if it's we change something around with this player game 33:18.590 --> 33:19.110 object. 33:19.110 --> 33:20.550 So it's gonna be save. 33:20.550 --> 33:25.670 And now I'm gonna press Ctrl s on my keyboard in order to save my project.
